Secondary cosmic rays in the NUCLEON space experiment

Abstract

The NUCLEON space observatory is a direct cosmic ray spectrometer designed to study cosmic ray nuclei with $Z=1-30$ at energies $10^{12}-10^{15}$ eV. It was launched as an additional payload onboard the Russian Resource-P No. 2 satellite. In this work B/C, N/O and subFe/Fe ratios are presented. The experiment has worked for half of its expected time, so the data have preliminary status, but they already give clear indications of several astrophysical phenomena, which are briefly discussed in this paper.
